of valve, beyond which point the duct becomes smaller, with very 
thin, almost transparent walls. At the tip of the endomeral plate 
the duct divides into two branches, which extend a short distance 
beyond it. 
A careful study of the figures accompanying this article, as well as 
the original description of cephalosus and microgenitalis, will prove 
more enlightening than a detailed description. The original drawing 
for the male genitalia of cephalosus proves to be erroneous, and a cor- 
rected one is herewith given (fig. 23, 9). 
DISCOCORPUS CEPHALOSUS INTERMEDIUS, new subspecies

Types.—Male and female, adults, from Crypturellus idoneus, col- 
lected by the author at El Bosque, Sierra Perijé, Colombia, on June 14, 
1941; in U.S. National Museum. 
Diagnosis.—This race is closer to the nominate form than to furcu- 
lus. It differs from cephalosus as follows: The preantennal portion of 
the head is practically the same, as to shape and width, but the temples 
are less convex laterally, and they extend farther posteriorly on each 
side of prothorax. There are minute differences in shape, size, and 
proportions of the various body segments which are too slight to 
enumerate, the chief distinguishing character of the race being the 
male genitalia (see fig.), which differ considerably from both cepha- 
losus and furculus. ‘The endomeral plate is of the type of cephalosus, 
but much wider posteriorly and of distinct shape, while the seminal 
duct is more like that of furculus, except that it is not bipartite. The 
paramers and basal plate also present differences. There is no trace 
of a scent gland in this genus.
